“…Chamaillé‐Jammes et al (2014) showed that MD inspect and respond differently to different predators' olfactory cues, and both human and mammalian predators utilize wind direction and other mechanism to minimize scent detection by deer (Cherry & Barton, 2017; Zagata & Haugen, 1974). In other ungulates, olfactory reception is associated with sexual activity (Cann et al, 2019), maternal behaviour (Blank & Yang, 2017; Keller & Lévy, 2012), territory choice (Deutsch & Nefdt, 1992), predator response (Kuijper et al, 2014; Wikenros et al, 2015) and foraging (Hirata & Kusatake, 2021). Low differentiation ( F ST ) but high diversity (π) of olfactory receptors in deer is consistent with their biology and behaviour and would be expected to be under strong selection pressures.…”

Speciation without gene‐flow in hybridizing deer

Under the ecological speciation model, divergent selection acts on ecological differences between populations, gradually creating barriers to gene flow and ultimately leading to reproductive isolation. Hybridisation is part of this continuum and can both promote and inhibit the speciation process. Here, we used white‐tailed (Odocoileus virginianus) and mule deer (O. hemionus) to investigate patterns of speciation in hybridizing sister species. We quantified genome‐wide historical introgression and performed genome scans to look for signatures of four different selection scenarios. Despite ample modern evidence of hybridisation, we found negligible patterns of ancestral introgression and no signatures of divergence with gene flow, rather localized patterns of allopatric and balancing selection were detected across the genome. Genes under balancing selection were related to immunity, MHC and sensory perception of smell, the latter of which is consistent with deer biology. The deficiency of historical gene‐flow suggests that white‐tailed and mule deer were spatially separated during the glaciation cycles of the Pleistocene and genome wide differentiation accrued via genetic drift. Dobzhansky‐Muller incompatibilities and selection against hybrids are hypothesised to be acting, and diversity correlations to recombination rates suggests these sister species are far along the speciation continuum.

“…In addition to the previously mentioned factors, further sensory properties of the feed influence feeding behaviour and taste preference. Cattle also use sight, smell, and haptics for feed selection 51 , 52 . In the current study, all measures were taken to influence taste solely and not the appearance, smell or haptics of the feed.…”

The aim of the study was to investigate the influence of intraperitoneal N-arachidonoylethanolamide (AEA) on taste preference for feed and water, tongue taste receptor signalling (TAS1R2, GNAT3), and endocannabinoid (CNR1, CNR2, GPR55) and opioid (OPRD1, OPRK1, OPRM1, OPRL1) receptors in the amygdala and nucleus accumbens in periparturient cows. We conducted taste preference tests using unaltered, umami-tasting, and sweet-tasting water and feed, before and after calving. After calving, eight cows received AEA injections (3 µg/(kg bodyweight × day), 25 days), whereas eight control (CON) cows received saline injections. Tissue was sampled 30 days after calving. Before calving, both cow groups preferred sweet-tasting feed and umami-tasting water. After calving, only the AEA-treated group preferred sweet-tasting feed, whereas the CON group showed no clear taste preference. In the amygdala, the mRNA expression of CNR1, OPRD1 (left hemisphere) and OPRK1 (right hemisphere) was lower in AEA animals than in CON animals, whereas no differences were found in the nucleus accumbens and tongue taste receptor expression. In conclusion, AEA administration enhanced existing taste preferences and reduced the expression of specific endocannabinoid and opioid receptors in the amygdala. The results support endocannabinoid-opioid interactions in the control of taste-dependent feed preference in early lactating cows.

“…Selection for woodland shade by white-tailed deer during movement might be related to the relatively high-light levels of this forest environment and short-wavelength enrichment compared to forest shade (Endler, 1993). Other ungulates rely on vision to distinguish high- and low-quality forage (Hirata and Kusatake, 2020; Hirata and Kusatake, 2021) and potentially locate foraging patches from long distances using visual cues (Bergman et al, 2005). The ability of white-tailed deer to discriminate details of their environment, including potential forage patches, would be improved within the high-light levels of woodland shade.…”

Visual perception is dynamic and depends on physiological properties of a species visual system and physical characteristics of the environment. White–tailed deer (Odocoileus virginianus)are most sensitive to short– and mid–wavelength light (e.g., blue and green). Wavelength enrichment varies spatially and temporally across the landscape. We assessed how the visual perception of deer influences their movement decisions. From August–September 2019, we recorded 10–min locations from 15 GPS–collared adult male deer in Central Florida. We used Hidden–Markov models to identify periods of movement by deer and subset these data into three time periods based on temporal changes in light environments. We modeled resource selection during movement using path–selection functions and simulated 10 available paths for every used path. We developed five a priori models and used 10–fold cross validation to assess our top models performance for each period. During the day, deer selected to move through woodland shade, avoided forest shade, and neither selected nor avoided small gaps. At twilight, deer avoided wetlands as cloud cover increased but neither selected nor avoided other cover types. Visual cues and signals are likely more conspicuous to deer in short–wavelength–enriched woodland shade during the day, while at twilight in long–wavelength–enriched wetlands during cloud cover, visual cues are likely less conspicuous. The nocturnal light environment did not influence resource selection and likely has little effect on deer movements because its relatively homogenous. Our findings suggest visual perception relative to light environments is likely an underappreciated driver of behaviors and decision–making by an ungulate prey species.
